As the title says, in game i have no problem putting them on the rack, but the text doesnt appear when I hover over the object to take it off. Whats going on?

That normally occurs if the weapon rack trigger ref to is only the static weapon rack, the static also needs to reference the activator. Should solve the issue.

If the weapon is placed behind the collision geometry of the wall, you can't access the weapon. Try with tcl command in console, if you can access the weapon after that, it's the case. You can see and use the collision geometry in the editor by activating it in the view menu.

Edit: Some weapons have a flat collision geometry, like iron axe (the default weapon when coc at lvl 1) and then can be behind the collision geometry of a lot of walls.

thanks for the info guys

Problem solved, it was to do with the collision of the wall behind the rack, I just moved the rack a little bit forward.
